N2 - It is expected that more than 10 Billion USD will be spent in Istanbul in coming years on tunnel boring especially with EPB-TBMs. However, the geology of Istanbul is very complex. Geologic formations changing from Paleozoic to Cenozoic ages cause tremendous problems due to frequently changed rock formations and andésite and diabase dykes. This paper summarizes a universal model to predict the performance of EPB-TBMs which is created upon the data base collected from several projects. The model first is based on predicting field specific energy and power consumed of TBMs using geo-mechanicai properties of the excavated material and TBM diameter. Later net production rate is calculated using field specific energy and power consumed by TBM. A methodology to predict machine utilization factor permits to calculate daily advance rates. The validity of the model is tested using the data obtained from two recent metro tunnel projects.Grant: The data is analyzed within a research project sponsored by Turkish Scientific and Research Council (TÜBITAK), project No 112M859. This paper is a product of a research work carried out for Dogus Construction Company, and Gulermak-Kolin-Kalyon JV. The authors thanks to the representative of these corresponding companies and the municipality of Istanbul, without their help it would be impossible to write this paper.
